Welcome to our Weekly CTF Contest!

CTF Description:

In this era of cloud computing, from individuals, enterprises to large conglomerates, everyone is migrating towards the cloud. With this comes an unseen threat because Cloud environments are different from the traditional infrastructure.

With over millions of active customers, Amazon Web Services (AWS) is one of the most popular cloud service providers, and due to the same reason, it is of prime importance to hackers. Gaining access to one such corporate AWS account can cost a company in billions.

Before moving towards the exploitation phase, it is important to perform reconnaissance as effectively as possible. This CTF contest is focused on performing reconnaissance on a compromised AWS Account. You are provided with an assumed breach scenario where you already have the Access Key Id and AWS Secret Key of a read-only user account. Your task is to enumerate services such as EC2, DynamoDB, Lambda, API Gateway, S3, and Cloudwatch.

Objective:

Collect all seven flags.

Level:

Beginner.

Instructions:

  • Click on RUN to start the lab (takes approximately 25s).

  • Click on LAB LINK to view the Access Key Id and Secret Key of an AWS account. You can now use this with other tools to enumerate the running services in the AWS account and start uncovering the flags

  • Collect the seven flags hidden among the services: EC2, DyanmoDB, Lambda, API Gateway, S3, and Cloudwatch.

  • Apart from FLAG4, the flags are named as FLAG1, FLAG2, FLAG3, FLAG5, FLAG6, and FLAG7

  • One of the IAM users has excess privilege over a resource. FLAG4 is the ARN of that resource.

Rules:

  • Capture and verify 7 flags - FLAG1, FLAG2, FLAG3, FLAG4 (Resource ARN),  FLAG5, FLAG6 and FLAG7

  • Once you verify the flags, email attackdefense@pentesteracademy.com with a short report on the process and the email you used to register on this website.

  • Reply to our Twitter or LinkedIn posts to let us know you've submitted your report. 

  • This CTF contest will start on 0000hrs Oct 30, 2020 ET and end on 2359hrs Nov 03, 2020 ET.

  • The first 3 correct submissions will get a 30-day subscription to PentesterAcademy.

  • An additional 3 correct submissions will also get a 30-day subscription to PentesterAcademy. These will be picked randomly from the remaining correct submissions coming in till 2359hrs Nov 03, 2020 ET.

Technical Support for this Lab:

There is a reason we provide unlimited lab time: you can take as much time as you need to solve a lab. However, we realize that sometimes hints might be necessary to keep you motivated!

We currently provide technical support limited to:

  • Giving hints for a lab exercise
  • In rare circumstances, if you have totally given up (NO!!!) then tell you how to solve it. This will be limited to sharing the solution video or lab report
  • A lab exercise fails to load or has errors in it

If you need technical support, please email  attackdefense@pentesteracademy.com  clearly mention the name and link of the lab exercise and other essential details. The more descriptive you are, the faster we can help you. We will get back to you within 24 hours or less.
